Extension function
When M8161 is set to ON for making the extension function valid, a half-width alphanumeric character string specified
in is converted into ASCII codes, and transferred in turn only to low-order 8 bits (1 byte) of .
"H00" is stored in high-order 8 bits.

Caution
1. Number of occupied devices
1) While the extension function is OFF
- occupies as many devices as the number of characters divided by "2". (The decimal point is rounded
up.)
2) While the extension function is ON
- occupies as many devices as the number of characters in the character string.
2. When using RS (FNC 80), ASCI (FNC 82), HEX (FNC 83) and/or CCD (FNC 84) instructions
The extension function flag M8161 is also used for other instructions.
When using an instruction described above and the ASC instruction in the same program, make sure to set M8161 to
ON or OFF just before the ASC instruction so that M8161 does not apply to another instruction.
